If you plan to grow the woodland plant Yellow Waxbells in your garden then sow seeds following the last frost of spring. Simply cover the seeds with topsoil once sown. They like to grow in areas that have part shade and a cool well drained soil. Ideally the soil that yellow bells grow in should also be acidic and enhanced by the addition of organic matter.
If you plan to start growing Yellow waxbells (Kirengeshoma) indoors first, then the seeds can take from one to ten months to germinate at 12 to 18 degrees Centigrade. Once growing the plants should not be put out in the garden until after the last frost of the following spring. The Yellow waxbells plant should be spaced at abouut 75 cm apart.
Once established Yellow Waxbells be disturbed for at least four years; after that time more yellow waxbells can be had by division of the plants in the spring.
